are marked to other elements in 
. So, the domain would be:
Hence, Option A.
Answer:
0.57142857142
Step-by-step explanation:
If you would like to know if (3, 6) is a solution to the inequality x + y <= 9, you can calculate this using the following steps:
(3, 6) ... x = 3, y = 6
x + y <= 9
3 + 6 <= 9
9 <= 9
Result: (3, 6) is a solution to the inequality x + y <= 9.
